ExxonMobil Guyana Limited (EMGL) has commenced subsea pipeline inspection activities for Guyana’s Gas-to-Energy (GtE) project, stretching from the West Coast of Demerara to offshore sections within the country’s exclusive economic zone (EEZ).
According to a notice from the Maritime Administration Department (MARAD) on May 25, inspections began on May 27 and will continue until August 15.
“The Inspection Area commences from the west coast of Demerara, approximately 2.15 nautical miles (4 kilometers) to 4.32 nautical miles (8 Kilometres) along the pipeline and covers an area of 5.6 square nautical miles (18.2 square kilometers),” MARAD said.

The notice stated that the inspection campaign will involve the vessels Telesto, DN 87, Gilligan Island, Rainbow Dolphin, and Sea Ark-SSC Adelaar, all of which will display the international signal for vessels engaged in subsea operations.
The subsea inspection work forms part of ongoing preparations for the GtE development, which is designed to transport associated natural gas from ExxonMobil’s offshore Stabroek Block operations to Wales, West Bank Demerara.
The first phase of the project includes a natural gas liquids (NGL) separation plant and a 300-megawatt gas-fired power plant. The facilities are intended to generate lower-cost electricity and produce liquefied petroleum gas for domestic use.
The infrastructure is being developed onshore by U.S.-based contractor Lindsayca, which continued execution of the project after the exit of its original joint venture partner, CH4. Although the project was initially targeted for completion in 2024, the timeline was revised following construction delays.

The Guyana government has indicated that the first gas turbine is expected to come online by the end of 2026, with all turbines fully commissioned during the first quarter of 2027. Combined-cycle operations are targeted for completion by June 2027.
Plans for a second phase of the Gas-to-Energy project include a pipeline link to ExxonMobil’s proposed Hammerhead development offshore Guyana, with a second NGL facility and an additional 300-megawatt power plant.

ExxonMobil operates Guyana’s Stabroek Block with a 45% stake, with co-venturers Hess, owned by Chevron (30%), and CNOOC (25%). The oil major has discovered an estimated 11 billion oil-equivalent barrels there.
